Gabor Szabo will be giving a talk at YAPC::NA_2012 described as:
Code refactoring is “disciplined technique for restructuring an
existing body of code, altering its internal structure without
changing its external behavior”. It is needed to ensure your code
remains readable while growing in size and scope.
It is needed if you have some old code base that needs improvement
and after every period of intense development when you “did not
have the time to properly design your code”.
There are several patterns in refactoring, some of them you might
already practice without knowing the name.
The most obvious is when you use a variable $x and suddenly you
realize it could have a more descriptive name.
If you change all the occurances of $x to this better name, without
changing anything else in the code, that’s already refactoring.
We will see several patterns for refactoring Perl code. We see
examples doing them manually and we’ll try to automate them as
well.
